What is defined as a hearing impairment?

A hearing impairment is characterized as a condition where an individual experiences a loss of hearing that permits some sound reception but does not equate to total deafness. This definition encompasses a wide range of hearing loss, from mild to moderate levels, where individuals may still perceive certain sounds or frequencies, which can significantly impact communication and social interaction.

The option highlighting a total inability to hear refers specifically to deafness, which does not encompass the broader category of hearing impairments where some level of sound perception exists. The notion of amplification relates to the extent and degree of hearing loss rather than defining the condition itself, while temporary hearing loss describes a situation that can improve, which does not align with the more persistent nature of most hearing impairments. Hence, the distinction made in the correct answer captures the essence of what a hearing impairment entails—functional hearing loss with potential sound reception capabilities.
